Reasons for rapid expansion in population can be accredited to several factors such as fertility, mortality, migration, and marriage. The years between 1811 and 1821 had the most rapid population growth where it reached 17 per cent per decade.

Poverty is believed to be the leading cause of overpopulation. A lack of educational resources, coupled with high death rates leading to higher birth rates, result in impoverished areas seeing large booms in population.

The Causes of Overpopulation

• Falling Mortality Rate. The primary (and perhaps most obvious) cause of population growth is an imbalance between births and deaths.
• Underutilized Contraception.
• Lack of Female Education.
• Ecological Degradation.
• Increased Conflicts.
• Higher Risk of Disasters and Pandemics.

In the following pages we shall discuss seven adverse consequences of high fertility and rapid population growth: (1) effects of large families on child development, (2) educational problems, (3) lags in new technology, (4) increased inequities in agriculture, (5) unemployment and underemployment, (6) urbanization and …

Population growth is the increase in the number of people living in a particular area. Since populations can grow exponentially, resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation and decreasing biodiversity.

Unsustainable population growth and lack of access to reproductive health care also puts pressure on human communities, exacerbating food and water shortages, reducing resilience in the face of climate change, and making it harder for the most vulnerable communities to rise out of intergenerational poverty.

Ignorance: Education plays a very important role in the population growth control. Because of early marriage, females produce more children thereby increasing the population. Uneducated people have less opportunity for employment. They cannot provide nutritious food to their children due to their low income.

The cost and prices rise which raise the cost of living of the masses. This brings the standard of living low. Poverty breeds large number of children which increases poverty further and vicious circle of poverty. Thus, the consequence of population growth is to lower the standard of living.

The increasing population numbers and growing affluence have already resulted in rapid growth of energy production and consumption in India. The environmental effects like ground water and surface water contamination; air pollution and global warming are of growing concern owing to increasing consumption levels.

Rapid growth has led to uncontrolled urbanization, which has produced overcrowding, destitution, crime, pollution, and political turmoil. Rapid growth has outstripped increases in food production, and population pressure has led to the overuse of arable land and its destruction.

The population is one of the important factors which helps to balance the environment, the population should in a balance with the means and resources. If the population will be balanced, then all the needs and demand of the people can be easily fulfilled, which helps to preserve the environment of the country.

Answer. population control and sustainability is vital in the health of a country’s economy and well being . workers are needed to maintain its infrastructure and services thus, the population must be maintained at a happy medium.

The quantity, quality, structure, distribution, and movement of a population can help or hinder the rate of economic development. A developed country with low population density and a low percentage of employable people needs an increase in population in order to keep up with economic development.

With rapidly growing population, it becomes difficult to manage the adjustments that accompany economic and social change. Urbanisation in UDCs creates such problems as housing, power, water, transport, etc. Besides, growing population threatens permanent environmental damage through urbanisation in some rural areas.

Growth of populations according to exponential (or J-curve) growth model (left) and logistic (or S-curve) growth model (right).

The Population Institute estimates that a 70 per cent increase in food production will also have to take into account increases in energy prices, as well as factors such as the groundwater depletion, the loss of farmland to urbanization, and potential flooding and droughts caused by climate change.

Technology can support improved economic growth and social well-being; effective harvest and post-harvest practices to minimize food loss; effective storage and conservation practices to increase the value of harvested products; identification of high value added products to improve economic gains for processors and …

The growth of world population in this period was responsible for 52% of the energy growth, while growth in per capita energy use was responsible for 48% (excluding causal connections between population and energy use per capita).
